[0078] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0079] As shown in Figure 1, a communication system 100 includes a terminal 101 and a network device 102, wherein the network device includes at least one of the following: an access network device and a core network device. The terminal can communicate with one or more network devices. For example, in the embodiments described below, the first cell and the second cell can be cells of the same network device, or the first cell and the second cell can be cells of different network devices.

[0080] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

The access network device may include an evolved NodeB (eNB), a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and at least one of an access node in a Wi-Fi system, but is not limited thereto.

[0082] In some embodiments, a core network device may be a device including one or more network elements, or may be multiple devices or device groups, each including all or part of the one or more network elements. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0083] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0084] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0085] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0086] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0087] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0088] In some embodiments, during the communication process with the terminal, the network device may send first information to the terminal, such as a system information block (SIB), a physical downlink channel, a reference signal, etc.

[0089] During this process, the network device may suspend sending the first information to the terminal for some reason. For example, if the terminal requests the network device to send the first information, the network device will send the first information. In this case, the status of the first information can be called on demand. Alternatively, the network device may suspend sending the first information to the terminal based on the cell communication status. In this case, the status of the first information can be called on demand.

[0090] It should be noted that the meaning of the first information being in an on-demand state is not limited to the network device sending the first information only when the terminal requests the first information.

[0091] In some embodiments, from the perspective of a network device, the first information being in an on-demand state may mean that, although the network device has sent a configuration of the first information to a terminal, the network device has stopped sending the first information to the terminal based on the configuration, and only continues to send the first information to the terminal based on the configuration after receiving a request from the terminal requesting the network device to send the first information. The first information being in a non-on-demand state may mean that the network device has sent a configuration of the first information to the terminal and sends the first information to the terminal based on the configuration.

[0092] In some embodiments, from the perspective of the terminal, the first information being in an on-demand state may mean that although the network device has sent the configuration of the first information to the terminal, the terminal has not received the first information from the network device based on the configuration. When the terminal needs to obtain the first information, the terminal sends a request message to the network device requesting the network device to send the first information; the first information being in a non-on-demand state may mean that the network device has sent the configuration of the first information to the terminal, and the terminal can receive the first information based on the configuration.

[0093] In some embodiments, based on the difference of the first information, the network device may send the first information to the terminal in different ways. For example, the first information may be sent through broadcast, multicast, groupcast, unicast, etc., and this disclosure does not limit this.

[0094] It can be seen that since the first information can be in both on-demand and non-on-demand states, the network device will suspend sending the first information to the terminal for the first information in the on-demand state. When the terminal needs to obtain the first information in the on-demand state, it needs to send a request message to the network device to request the network device to send the first information to the terminal.

[0095] FIG2 is an interactive schematic diagram showing a method for sending information according to an embodiment of the present disclosure.

[0096] As shown in FIG2 , the information sending method may include the following steps:

[0097] In step S201, first configuration information is obtained.

[0098] The manner in which the terminal obtains the first configuration information will be exemplarily described in subsequent embodiments and will not be described in detail here.

[0099] In step S202, request information is sent to a network device in the first cell according to the first configuration information, wherein the request information is used to request the network device to send a system information block SIB1 in an on-demand state in the first cell.

[0100] In some embodiments, the first configuration information may include information such as frequency domain resources and / or time domain resources, and the terminal may send the above request information to the network device on the time domain resources and / or frequency domain resources determined according to the first configuration information.

[0101] According to an embodiment of the present disclosure, for SIB1 in an on-demand state in the first cell, the terminal can obtain the first configuration information, and then when it is necessary to obtain SIB1, it can send a request information to the network device on the first cell according to the first configuration information to request the network device to send SIB1 to the terminal on the first cell, so as to ensure that the terminal can successfully obtain SIB1.

[0102] It should be noted that whether SIB1 is in the on-demand state can be indicated by the network device or determined by the terminal based on the reception of SIB1. For example, if the terminal does not receive SIB1 on the first cell in the first number of SIB1 reception windows (which can be continuous or non-continuous windows), it can be determined that SIB1 is in the on-demand state.

[0103] In some embodiments, when SIB1 is in the on-demand state, since SIB1 is relatively important information, under normal circumstances, SIB1 will not enter the on-demand state. However, the network device can still make SIB1 enter the on-demand state for certain needs. For example, the network device needs to enter the Network Energy Saving (NES) mode. Then, for energy saving considerations, the sending of SIB1 in the first cell can be suspended, so that SIB1 in the first cell enters the on-demand state.

[0104] Therefore, in some embodiments, the request information sent by the terminal to the network device to request the network device to send SIB1 can also be called a wake-up signal (WUS), which can be used to wake up the network device from NES mode. After the network device is woken up from NES mode, it can continue to send SIB1. Of course, in some embodiments, the network device can also send SIB1 based on the request information when it is in NES mode.

[0105] In some embodiments, the network device may suspend sending SIB1 to the terminal in the first cell. When the terminal performs a cell search, the terminal may attempt to access the first cell. While trying to access the first cell, the terminal may attempt to receive SIB1 in the first cell. If the terminal cannot receive SIB1 in the first cell, the terminal will not be able to be configured with resources for requesting information by the network device in the first cell in a conventional manner.

[0106] Therefore, in an embodiment of the present disclosure, when the terminal determines that SIB1 on the first cell is in the on-demand state, the first configuration information for sending request information on the first cell can be obtained by a method other than receiving configuration information of the network device on the first cell.

[0107] The following uses several embodiments to exemplify how the terminal obtains the first configuration information used to send request information on the first cell when the SIB1 on the first cell is in the on-demand state.

[0108] In some embodiments, the terminal may first attempt to receive SIB1 on a first cell. If SIB1 is not received on the first cell, the terminal may attempt to receive system information on a second cell, which is a different cell from the first cell.

[0109] Among them, the terminal can determine whether SIB1 can be received on the first cell in multiple ways. For example, if SIB1 is not received / detected within the first number of system information reception time windows, the terminal can determine that SIB1 is not received on the first cell, or that SIB1 of the first cell is not received.

[0110] If system information can be received on the second cell, the first configuration information corresponding to each cell in the cell set can be determined based on the system information, wherein the cell set includes the first cell, and then the first cell can be determined in the cell set, and the first configuration information for sending the request information on the first cell can be determined.

[0111] In some embodiments, when attempting to access a first cell, the terminal may attempt to receive SIB1 on the first cell. If SIB1 is not received on the cell, the terminal may attempt to receive system information on at least one second cell. After the terminal receives the system information on the second cell, the system information may include a cell set and first configuration information corresponding to each cell in the cell set. The terminal can then determine, based on the system information, that the first cell corresponds to the first configuration information, and then send a request message to the network device based on the first configuration information.

[0112] In some embodiments, the second cell may be any cell from which the terminal can attempt to receive system information. In some embodiments, the second cell may be a cell predetermined by the terminal. For example, a network device may pre-configure the terminal, or the terminal may pre-determine a cell group based on a protocol agreement. The cell group includes one or more second cells. The system message of each second cell in the cell group includes the aforementioned cell set and the first configuration information corresponding to each cell in the cell set. Alternatively, the system message of any cell in the cell group may include the first configuration information corresponding to the first cell.

[0113] In this embodiment, the network device can configure a cell set and the first configuration information corresponding to each cell in the cell set in the system information of each cell. Accordingly, it can be ensured that when the terminal receives system information on any second cell other than the first cell, it can successfully obtain the first configuration information corresponding to the first cell (that is, the first configuration information used to send request information on the first cell).

[0114] For example, the cell set and the first configuration information corresponding to each cell in the cell set can be carried in the system information in the form of a list. For example, in the list, a cell can correspond to one or more first configuration information, and each cell has corresponding first configuration information.

[0115] In some embodiments, the terminal may determine that it needs to receive SIB1 in the first cell (for example, the terminal determines that the first cell is the first cell attempted to access during the cell search process), and then the terminal attempts to receive SIB1 on the first cell. If the terminal does not receive SIB1 on the first cell, it may attempt to receive system information on the second cell, where the second cell may be any cell in which the terminal can attempt to receive system information, or it may be a cell belonging to a cell group. For the concept of the cell group, please refer to the previous embodiment and will not be repeated here.

[0116] The system information of the second cell may include a cell set and the first configuration information corresponding to each cell in the cell set, so that after the terminal receives the system information in the second cell, it can determine the first configuration information corresponding to the first cell based on the system information, and then send a request information to the network device based on the first configuration information to request the network device to send SIB1 in the first cell, so that the terminal can successfully receive SIB1 in the first cell.

[0117] According to this embodiment, when the SIB1 in the first cell is in an on-demand state, the terminal may attempt to receive system information on at least one second cell other than the first cell. Since the system information of each cell is configured with the first configuration information corresponding to each cell in the cell set, it is ensured that the terminal can obtain the first configuration information for sending request information on the first cell from the received system information, so that when the subsequent terminal needs to obtain the SIB1 on the first cell, it can send request information to the network device in the first cell according to the first configuration information to request the network device to send SIB1 on the first cell.

[0118] Among them, the terminal receives system information on the second cell, and can first determine the relevant configuration of the system information based on the SSB on the second cell (for example, the master information block (MIB) in the SSB), and then receive the system information on the second cell according to the relevant configuration of the system information.

[0119] In this embodiment, the terminal attempts to receive system information on the second cell, and sends request information to the network device on the first cell according to the first configuration information, which can be performed when the terminal is in a non-connected state (such as an idle state or an inactive state).

[0120] In some embodiments, the first cell is the first cell attempted to be accessed during the cell search process.

[0121] For example, during the cell search process, the terminal can measure the downlink signals of multiple cells, where the downlink signals include at least one of the following: synchronization signal block (SS (Synchronization Signal) and PBCH (Physical Downlink Broadcast Channel) Block, SSB); channel state information reference signal (Channel State Information Reference Signal, CSI-RS).

[0122] The terminal can then sort multiple cells according to the strength of the downlink signal (such as Reference Signal Receiving Power (RSRP)). For example, the cell with a stronger downlink signal strength is ranked higher, and the terminal will try to access the cell with a higher ranking earlier during the cell search process.

[0123] Therefore, in some embodiments, the first cell may be the cell with the largest signal strength among multiple cells determined by the terminal during the cell search process. The terminal may first try to access the first cell. When it is determined that the SIB1 in the first cell is in the on-demand state, the terminal may try to receive system information on a second cell other than the first cell according to the signal strength.

[0124] In some embodiments, during the cell search process, the terminal receives system information on a second cell following the first cell.

[0125] For example, the terminal receives system information on the second cell that it attempts to access next during the cell search process; if the system information is not received on the second cell that it attempts to access, the step is repeated until it is determined that the system information is received on the second cell that it attempts to access.

[0126] It should be noted that the method for determining the first cell is not limited to determination based on RSRP ranking and can also be determined by other methods. For example, the first cell can be a cell agreed upon in the protocol; for example, the first cell can be the cell with the largest or smallest identifier among the neighboring cells of the serving cell; for example, the first cell can be the cell determined by the terminal during cell handover based on the indication of the source cell. This disclosure is not limited to this.

[0127] For example, the first cell may be the cell with the highest signal strength among multiple cells determined by the terminal during a cell search process, and the second cell may be the cell with a lower signal strength than the first cell among the multiple cells. When there are multiple second cells, the terminal may first receive system information from the second cell that is attempted to be accessed next to the first cell. If the system information is not received, the terminal may then receive system information from the second cell that is attempted to be accessed next, until the system information is received.

[0128] For example, the multiple cells are n cells, namely cell#1 to cell#n. The signal qualities of the n cells measured by the terminal during the cell search process are cell#1, cell#2, cell#3, ..., cell#n.

[0129] During the cell search process, the terminal may first try to access cell#1 and receive SIB1 on cell#1. If it is determined that SIB1 on cell#1 is in the on-demand state, it may try to receive SIB1 on cell#2. If SIB1 cannot be received on cell#2, it may continue to try to receive SIB1 on cell#3, and so on, until SIB1 is received on a cell among the n cells.

[0130] In some embodiments, if the terminal fails to receive system information on n cells or fails to complete the cell search within a predetermined time, the terminal may generate a prompt message, and / or wait for a period of time before performing the cell search again, and / or perform cell reselection.

[0131] In some embodiments, the terminal may receive system information on multiple cells, and determine first configuration information corresponding to each cell in a cell set based on the system information received on at least one cell among the multiple cells, where the cell set includes the first cell.

[0132] In this embodiment, the network device can configure a cell set and the first configuration information corresponding to each cell in the cell set in the system information of each cell. Accordingly, it can be ensured that when the terminal receives system information in any cell among multiple cells, it can successfully obtain the first configuration information corresponding to the first cell (that is, the first configuration information used to send request information in the first cell).

[0133] For example, the cell set and the first configuration information corresponding to each cell in the cell set can be carried in the system information in the form of a list. For example, in the list, a cell can correspond to one or more first configuration information, and each cell has corresponding first configuration information.

[0134] According to this embodiment, the terminal may not first determine whether the SIB1 on a certain cell is in an on-demand state, but directly try to receive system information on multiple cells. Since the system information of each cell is configured with the first configuration information corresponding to each cell in the cell set, it is ensured that the terminal can obtain the first configuration information for sending request information on the first cell from the system information received on any cell, so that when the terminal subsequently needs to obtain the SIB1 on the first cell, it can send a request information to the network device in the first cell according to the first configuration information to request the network device to send SIB1 on the first cell.

[0135] Among them, the terminal receives system information on multiple cells, and can first determine the relevant configuration of the system information based on the SSB on each cell in the multiple cells (for example, the MIB in the SSB), and then receive the system information on the corresponding cell according to the relevant configuration of the system information.

[0136] In this embodiment, the terminal attempts to receive system information on multiple cells, and sends request information to the network device on the first cell according to the first configuration information, which can be performed when the terminal is in a non-connected state (such as an idle state or an inactive state).

[0137] In some embodiments, the terminal performs cell searches on multiple cells in parallel; wherein, upon receiving system information on at least one of the multiple cells, access to the multiple cells is stopped.

[0138] The difference from the traditional cell search process is that in the traditional cell search process, the terminal performs the cell search process cell by cell, for example, attempting to access each cell one by one, attempting to access one cell each time; while in this embodiment, the terminal can perform cell searches on multiple cells in parallel, thereby attempting to access multiple cells at the same time, and thus can attempt to receive system information sent by multiple cells.

[0139] However, the terminal attempts to access multiple cells simultaneously mainly to ensure that it can obtain system information. Ultimately, the terminal still only accesses one cell. Therefore, after receiving system information in any of the multiple cells, the terminal can stop the process of accessing multiple cells. For example, this can be called early termination. In this case, the terminal stops subsequent processes of attempting to access multiple cells, such as initiating random access, to avoid wasting communication resources.

[0140] In some embodiments, the terminal may determine the signal strength of each cell among a plurality of cells; and determine the first cell among the plurality of cells according to the signal strength.

[0141] The terminal performs cell searches on multiple cells in parallel, and after receiving system information from any of the multiple cells, it can stop accessing the multiple cells, and then measure the downlink signals of each of the multiple cells to determine the signal strength of each cell, and determine the resident cell among the multiple cells based on the signal strength, which can be called the first cell, for example.

[0142] In this case, even if the SIB1 in the first cell is in an on-demand state, the terminal can determine the first configuration information for sending the request information in the first cell from the received system information, and then when it is necessary to obtain SIB1, send the request information on the first cell according to the first configuration information to request the network device to send SIB1 on the first cell.

[0143] Of course, if the SIB1 in the first cell is not in the on-demand state, the terminal can receive SIB1 according to the configuration information of SIB1 (for example, determined according to the SSB of the first cell) without sending request information to the network device.

[0144] In some embodiments, the system information carrying the cell set and the first configuration information corresponding to each cell in the cell set in the above embodiment may include at least one of the following:

[0145] Remaining Minimum System Information (RMSI);

[0146] Other System Information (OSI).

[0147] In some embodiments, if the terminal fails to receive system information on multiple cells or fails to complete the cell search within a predetermined time, the terminal may generate a prompt message, and / or wait for a period of time before searching the cell again, and / or reselect the cell.

[0148] In some embodiments, when the terminal is in a connected state, the terminal can obtain first configuration information according to terminal-specific signaling sent by a network device, wherein the first configuration information is not released and / or rewritten after the terminal enters a non-connected state.

[0149] Before the terminal resides in the first cell, it can first enter a connected state in a certain cell (which can be a cell other than the first cell or the first cell). When the terminal is in the connected state, the network device can indicate the first configuration information to the terminal through terminal-specific (UE dedicated) signaling.

[0150] Among them, the process of the terminal accessing the connected state on a certain cell may include, for example: the terminal performs cell search, receives SSB on cell A, receives SIB1 on cell A according to the received SSB, and then the terminal initiates random access in cell A to access cell A.

[0151] For example, the terminal-specific signaling includes at least one of the following: Radio Resource Control (RRC) signaling, Downlink Control Information (DCI), and Media Access Control Control Element (MAC CE).

[0152] In some embodiments, when the terminal is in a non-connected state, the terminal sends request information to the network device on the first cell according to the first configuration information.

[0153] Different from the traditional way of processing configuration information by the terminal, in this embodiment, the first configuration information received by the terminal in the connected state will not be released or rewritten when entering the non-connected state. Therefore, when the terminal attempts to access the first cell in the non-connected state, if it is determined that the SIB1 in the first cell is in the on-demand state, the terminal can send a request information on the first cell according to the first configuration information when it needs to obtain SIB1, so as to request the network device to send SIB1 on the first cell.

[0154] For example, the terminal can mark the first configuration information to distinguish it from other configuration information, so that after the terminal enters the unconnected state from the connected state, other configuration information can still be released and / or rewritten, but the first configuration information will not be released and / or rewritten.

[0155] In some embodiments, the first configuration information indicated by the network device to the terminal when the terminal is in a connected state can be at a granularity of bandwidth fractions, i.e., the first configuration information is per BWP, or at a granularity of cells, i.e., the first configuration information is per cell. Of course, the granularity is not limited to the above two examples, and this disclosure does not limit this.

[0156] In some embodiments, if the terminal fails to complete the cell search within a predetermined time period, the terminal may generate a prompt message, and / or wait for a period of time before performing the cell search again, and / or reselect a cell.

[0157] In any of the above embodiments, since the network device needs to receive the request information sent by the terminal on the first cell based on the first configuration information, the network device also needs to know the first configuration information. For example, the first configuration information can be sent by the network device in system information, or sent by the network device to the terminal through terminal-specific signaling; for example, the first configuration information is obtained by the network device from other network devices (for example, obtained through an interface between network devices), the system information sent by the other network devices carries the first configuration information, or the terminal-specific signaling sent by the other network devices to the terminal carries the first configuration information.

[0158] The communication method involved in the embodiments of the present disclosure may include at least one of steps S201 and S202. For example, step S201 may be implemented as an independent embodiment, step S202 may be implemented as an independent embodiment, and steps S201+S202 may be implemented as independent embodiments, but are not limited thereto.
